No matter which coating process is used, the technical requirements of the substrate are getting higher and higher.Most steel base color coating board requires flat zinc flower, zero zinc flower hot galvanized steel roll or galvanized steel coil, in recent years have increased with hot galvanized aluminum, alloy coated steel plate as substrate trend; film color coating board with cold rolled roll as substrate, some high-grade products with stainless steel substrate.No matter which kind of substrate is used, its surface, plate shape and size accuracy have high requirements.
Galvanized plate zinc flower structure after good galvanized plate color coated product surface quality is higher, more suitable for special purposes.Some post-processing products have higher requirements for the surface quality of galvanized plate, which need to be treated on the basis of small zinc flower, which completely eliminates zinc flowers. This substrate is called the light of zinc flower, flatness is very high, and the use range of products after coating is more broad.The cold-rolled sheet factory of Esteel Company is equipped with optical finishing device in the galvanized unit. The galvanized sheet produced by light is more suitable for color coating process.
